Manganese sand filter media is made of high-quality manganese sand ore, with dense grains, high mechanical strength, strong chemical activity, not easy to break, and insoluble in water.
It is processed into sand by washing, grinding, impurity removal, crushing, drying, magnetic separation, screening, dust removal, and other processes. Then the processed manganese sand is blended according to a certain gradation.
It has the most ideal gradation ratio of water treatment filter material, so that it has the largest specific surface area, the strongest interception capacity, the largest oxidation catalysis effect, and the smallest backwash loss rate per unit volume.
Manganese sand filter material is dark brown in appearance, nearly round, the main component is manganese dioxide, and the content is between 25% and 45%.
